Hello,

I am currently working on the SAP desktop application which consist of 2 page scroll down.

The situation is that

.1. I need to select the line number from the software, scroll down and then edit the quantity. For editing the quantity I need to scroll down the outside section of the page and then I able to edit the quantity.(there are 2 sections and both contain scrolls 1. Contains description of the products 2. Contains the main part where you see the "quantity section " and you write the quantity in that section )
2. After editing the quantity I need to scroll up again to select the 2nd description and edit the quantity for 2 product

So how do I cope with multiple scrollings in SAP software ?? how do I do that
